How Is the Nomenclature in 13C(alpha,n)16O Read and What Do Alpha and n Mean?

AI Thread Summary
The nomenclature 13C(alpha,n)16O refers to a nuclear reaction where carbon-13 interacts with an alpha particle to produce oxygen-16 and a neutron. In this context, "alpha" denotes an alpha particle, equivalent to a helium-4 nucleus, while "n" represents a neutron. The discussion highlights the significance of asymptotic giant branch (AGB) stars, specifically those with masses between 2 to 4 solar masses, as key producers of the s-process isotope 182Hf in the Galaxy. This production is influenced by the reactions involving both 13C(alpha,n)16O and 22Ne(alpha,n)Mg. Understanding this nomenclature is essential for grasping the processes that contribute to nucleosynthesis in stellar environments.

How is this nomenclature read and what is the meaning of the alpha and the n? quote below

In terms of the absolute 182Hf abundance, howevever, only AGB (asymptotic giant branch) models of mass ~2 to 4 solar masses are major producers of s process 182Hf in the Galaxy, owing to the combined effect of the 13C(alpha,n)16O and 22Ne(alpha,n)Mg

You must be new to physics.

n stands for neutron
alpha stands for alpha particle, which is the same as a helium-4 nucleus (but with no electrons)

The notation 13C(alpha,n)16O is a shorthand form for the nuclear reaction 13C + α → 16O + n

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
