		Femtometre (in American English femtometer) is an SI measure of length that is equal to 10
		Its abbreviation is fm and is commonly used in measuring the diameter of atomic nuclei.
		In the parlance of particle physicists, a femtometre is often called a 'fermi' (same abbreviation), after the physicist Enrico Fermi.

	Accelerators: the ultimate microscope
		CERN physicists investigate the constituents of matter at the subatomic level, where the typical distances are of the order of the femtometre (0.000000000000001 m, or 10
		To be able to probe objects of such a small scale, physicists need other tools than your ordinary microscope.
		This means, oddly enough, that the smaller the details you want to look at, the larger the machine you will have to build.

		The mass of the electrons is small in comparison to the mass of the nucleus.
		The radius of a nucleon (neutron or proton) is of the order of 1 fm (femtometre = 10-15 m).
		The nuclear radius, which can be approximated by the cubic root of the mass number times 1.2 fm, is less than 0.01 % of the radius of the atom.

	CERN Courier - Heavy implications for the f - IOP Publishing - article
		The programme has also allowed a new productive partnership to develop between high-energy physicists and nuclear physicists, and it has considerably extended the number of scientists using CERN as a research base, with new research centres, some of them from far afield, joining the CERN research programme.
		Estimates of the energy density established when the colliding nuclei coalesce point to several giga-electron-volts per cubic femtometre (CERN CourierNovember 1999 p8), suggesting that the theoretically expected critical energy threshold has been crossed.
		One important quark signature is the J/psi particle, which is made of a charm quark and its antiquark.

		Microscopes using light reveal details of micrometre dimensions.
		Swift particle beams have probed objects of nanometre (1897), picometre (1932), femtometre (1955) and attometre (1999) sizes.
		Studies of structure below the attometre scale during this century promise to increase greatly our understanding of the universe.

		LISA and the next generation of space-based laser interferometers require gravitational reference sensors (GRS) to provide distance measurements to picometre precision for LISA, and femtometre precision for the proposed Big Bang Observatory (BBO).
		We describe a stand-alone GRS structure that has the benefits of higher sensitivity and ease of fabrication.
