For a hydrogen-like atom, give all possible spectral terms for n=2 and n=3.
Define binding energy. Calculate the binding energy per nucleon of ⁵⁶₂₆Fe. Given: M(⁵⁶₂₆Fe)=55.934932; m_n=1.008665u; m_p=1.007825u.
The disintegration constant of ²³⁸U is 4.87×10⁻¹⁸s⁻¹. Calculate its half life(in years). Also calculate the number of disintegration per second from 1 gram of Uranium. It is given that Avogadro's number= 6.02×10²³
The wavefront for a particle is defined by:
Ψ(x)= {Ncos(2πx/L) for -L/4≤x≤L/4
{0 otherwise
Determine:
i) the normalisation constant N
ii) the probability that the particle will be found between x=0 and x=L/8.
