I am undergraduate physics student,and I want to become a theoretical physicist.
I need some ideas about fields to look at it that can inspire me .
I do not have specific field that I like the most in physics..so I need your help
Homework Statement
I need to proof that Rodrigues’ formula satisfies Laguerre differential equation
Homework Equations
Rodrigues’ formula of Laguerre
Laguerre differential equation

Homework Statement
What are the partial half of 22Na for decay by
a)Ec
b) β+ emission
Homework Equations
λ=ln2/T1/2
The Attempt at a Solution
this what I do
T1/2 =2.602 Yr
λ=ln2/2.602
λ=0.266 yr-1what is the difference between
a)Ec
b) β+ emission
there is no Percentage of each decay type.!
Homework Statement
what is the mass in g of the activity?
(a)1μCi 241Am
Homework Equations
A = λN
λ = ln2 / T1/2
The Attempt at a Solution
A = λN
1μCi = λN
N=1μCi/λ
N = ( x /241 mol) × (6.022 × 1023 nuclei mol-1 )
1μCi/λ=( x /241 mol) × (6.022 × 1023 nuclei mol-1 )
X=1μCi (241)/λ(6.022×...
Homework Statement
If a radioactive sample of 59Fe (t1/2= 44.496 d) has an activity of 1000 disintegrations per minute, what weight of 59Fe is present?
Homework Equations
In an experiment one observes the characteristic Ka X-rays of two elements at energies of 6.930 and 7.478 eV. The higher energy line is due to Ni. What element is responsible for the lower energy line?
Legendre functions $Q_n(x)$ of the second kind
\begin{equation*}
Q_n(x)=P_n(x) \int \frac{1}{(1-x^2)\cdot P_n^2(x)}\, \mathrm{d}x
\end{equation*}
what to do after this step?
how can I complete ?
I need to reach this formula
\begin{equation*}
Q_n(x)=\frac{1}{2} P_n(x)\ln\left( \frac{...
