Generations in the workforce the recession, there has been a significant shift in Gen X moving to management roles. Perceptions of Gen X managers are high according to an online survey published by Ernst & Young. Out of 200 people, 57% of respondents believed that Gen X displayed each of the survey’s positive characteristics and were thought to be best at managing through difficult times. The Y generation, also referred to as "Millennials" were born around 1980 to 2000. They have been described in a report published by United Nations Joint Staff Pension Fund as the next big generation after the Baby Boomers. They
Spin echo laser spectroscopy and neutron scattering. Echoes were first detected in nuclear magnetic resonance by Erwin Hahn in 1950, and spin echoes are sometimes referred to as Hahn echoes. In nuclear magnetic resonance and magnetic resonance imaging, radiofrequency radiation is most commonly used. In 1972 F. Mezei introduced spin echo neutron scattering, a technique that can be used to study magnons and phonons in single crystals. The technique is now applied in research facilities using triple axis spectrometers. The spin echo effect was discovered by Erwin Hahn when he applied two successive 90° pulses separated by short time period, but detected
