Q1.

(a) What do you understand by tunneling through a barrier? A particle travelling with energy E along X-axis meets a potential barrier defined by w \endcases Derive an expression for reflection and transmission coefficient of the particle. रोधिका द्वारा सुरंगन से आप क्या समझते हैं? E ऊर्जा से X-अक्ष के साथ भ्रमण करने वाला कण
$ w \endcases
$
के लिए परिभाषित विभव रोधक से टकराता है। कण के परावर्तन एवं पारगमन गुणांक के लिए व्यंजक व्युत्पन्न करें।

Q2.

(a) Define Pauli matrices and show that they anticommute. Also show that σ_ + σ_- = 2(1 + σ_z) पॉली आव्यूह को परिभाषित करें तथा दर्शायें कि वे क्रम- अविनिमेय हैं। साथ ही सिद्ध करें σ_ + σ_- = 2(1 + σ_z).

Q3.

(a) The bands of a system are described by the expression
v = 19221 \cdot 2 + (1611 \cdot 3 u' - 49 \cdot 7 u'^2) - (1495 \cdot 7u'' - 31 \cdot 5u''2)
where u = v + 1/2. Calculate the position of 0, 0 band and discuss degradation of bands and their intensity distribution using Franck-Condon principle.
