Professor Kleppner and his group will pursue three major goals: (1) to interpret the laser spectroscopy of Rydberg atoms in magnetic fields in terms of classical chaos and to trace the relationship between the classical and quantal description of the electron motion, (2) determine the ground-state Lamb shift by making the world's most precise measurement of the Rydberg constant, using millimeter wave spectroscopy, (3) perform a precision measurement of the 1S-2S transition in hydrogen where the width of the line due to kinetic motion of the atoms has been vastly reduced by evaporatively cooling the sample.

克莱普纳教授及其小组将追求三个主要目标：（1）用经典混乱来解释磁场中雷德伯格原子的激光光谱检查，并追踪电子运动的经典和数量描述之间的关系，（2）通过使用Rydberg的最佳测量表来确定地下羔羊的范围，以确定地下羔羊的范围，使用Rydberg的最佳测量表，通过蒸发冷却样品，由于原子的动力学运动而导致的线宽度大大降低了线的宽度，因此在氢中的1S-2S过渡的测量。
