Mayer, Maria

All the previous discussion in this chapter has been concerned with absorption or emission of a single photon. However, it is possible for an atom or molecule to absorb two or more photons simultaneously from a light beam to produce an excited state whose energy is the sum of the energies of the photons absorbed. This can happen even when there is no intemrediate stationary state of the system at the energy of one of the photons. The possibility was first demonstrated theoretically by Maria Goppert-Mayer in 1931 [29], but experimental observations had to await the development of the laser. Multiphoton spectroscopy is now a iisefiil technique [30, 31].

In the 1930s, Maria Goppert-Mayer [12], theoretically predicted the process of an atom being raised to an excited state of energy equal to the sum of two simultaneously...

The theory of Bowden et al was disputed by W.A. Hargreaves (See p Alll-L of Vol lj, who proposed his own theory. This theory was favored by Dr J. Mayer, who worked at Explosives Plant, Villa Maria, Argentina. If Hargreaves theory were accepted, it would be difficult to explain the rejuvenation of aged Gelatin Dynamites, as was done at... 

Dr J.Mayer of Villa Maria, Argentina,discusses both the above theories and seems to favor the second one(Ref 4)... 

In 1960, the Mayers moved to the University of California at San Diego, where both could finally hold full professorships, his in chemistry and hers in physics. But shortly after arrival, Maria suffered a stroke and was troubled thereafter by poor health, succumbing finally (after a prolonged coma) in 1972. While continuing collaborative theoretical chemistry studies, Joseph Mayer helped to build the newly formed UCSD chemistry faculty to national prominence. He retired and remarried, then accepted a term of presidency of the American Physical Society (1973) and continued other professional activities until his death in 1983. 

Although his scientific contributions were naturally somewhat overshadowed by those of Maria, Joseph Mayer built a legacy of concepts and methods that influence many areas of modem physical chemistry research. 

Bodies and Teller presented a paper prepared jointly with Maria Goep-pert Mayer, on the original formation of the elements.
