1. When ultraviolet radiation of wavelength 58.4nm from a helium lamp is directed on to a sample of krypton, electrons are ejected with a speed of 1.59M m/s.Calculate the ionization energy of krypton. 計算游離能怎麼會出現有速度的公式? 還是說游離能會等於1/2mv^2 ? 這題答案是 I = 14.0 eV 2. By differentiation of the 2s radial wavefunction, show that it has two extrema in its amplitude, and locate them. 這一題答案是有兩個 r = 4a0 、r = 0 計算過程是用到機率??? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.137.67.125 ※ 編輯: starwish07 來自: 114.137.67.125 (05/26 20:47) ※ 編輯: starwish07 來自: 114.137.67.125 (05/26 23:12)

第二題的第二個r是等於0 已修正

第2題把2s radial wavefunction個式子微分後等於0, 解r

解 "r" ? 怎麼解? 式子裡面有個Z 這樣答案也會有Z...

第一題是求功函數(W)吧 入射光的動能=W+電子動能
